Interesting this would pop up on the day I was out in my front garden working and a group of boys and a girl (6 to 10 years old) were there on bikes. They teased one who didn’t know what 69 was, which I remember from my own time as an 8 year old. But now one boy had a phone so he pulled it out and looked up a tube site to everyone’s entertainment/bemusement/disinterest.
It’s like a WW2 convoy. You’re only as good at moderating content and controlling technology as the worst parent in your child’s friend group.
Coincidentally I saw some YouTube adverts in yesterday’s telegraph highlighting safety controls to stop what children can access.
